| Description |
Hydraulic fluids based on mineral oils, though have an optimum performance and technical requirements
as specified in the standards for hydraulic oils, fail to meet toxicity and biodegradability requirements.
Synthetic esters are known to have better biodegradability, lower inflammability, better lubricity and
fluidity, lower volatility and higher thermal and oxidation stability in comparison to mineral oils. These
properties can be further enhanced through molecular design to suit the practical applications. Therefore,
synthetic esters appear as promising candidates where environmental protection is of utmost importance.
Polyol and carboxylic acids (C6-C14)both pwre and their mixtures, were used for synthesizing esters. The
products were characterized for their physico-chemical properties and evaluated for their lubrication
performance. These were then compared with VG-22 grade fire resistant hydraulic fluids (FRHF). The
paper deals with the synthesis, characterization, and evaluation of the esters and discusses their potential
use as FRHF.
